Renewed prime time licence (6)
I believe the answer is:
permit
'licence' is the definition.
(I've seen this before)
'renewed prime time' is the wordplay.
'renewed' indicates anagramming the letters.
'time' becomes 't' (abbreviation).
'prime' is an anagram of 'permi'.
'permi'+'t'='PERMIT'
(Other definitions for permit that I've seen before include "Let; enabling document" , "Official document giving authorisation" , "Allow, sanction" , "Warrant" , "Allow, authorise" .)
